Abstract: 1,252,824. Aqueous dispersions of polyoxymethylene polymers or grafted polyoxymethylenes. FARBWERKE HOECHST A.G. 7 July, 1969 [6 July, 1968], No. 34056/69. Headings C3G and C3P. An aqueous polymer dispersion comprises from 5% to 60% by weight of at least one modified polyacetal having a reduced viscosity of 0-05 to 2 dl./g., which modified polyacetal is a homopolymer or co-polymer of formaldehyde or trioxane containing at most 50% by weight, calculated on the total number of acetal groups in the polymer molecule, of carboxylic and/or sulphonic groups, the size of the dispersed polymer particles being from 0-1 to 10 microns. The disperson is prepared by mixing a solution of tho polymer in an organic solvent with water and subsequently removing the organic solvent by distillation. The carboxylic and sulphonic groups may be introduced into the modified polyacetal by (a) forming a polymer containing carboxylic acid ester groups, e.g. a copolymer of trioxane with a comonomer containing both an ester group and a copolymerizable group or a terpolymer of trioxane, said comonomer and a lactone, and saponifying the resulting polymer, (b) polymerizing trioxane in the presence of a chain transfer agent containing an ester group and saponifying the polymer, (c) reacting an oxymethylene polymer containing terminal hydroxyl groups with an agent containing an ester-group e.g., an acrylate ester and saponifying the polymer or (d) grafting an ester of an unsaturated carboxylic acid on to an oxymethylene polymer and saponifying the polymer. A polyacetal containing ester groups may be saponified during the stage of forming the aqueous dispersion by adding alkali to the polymer solution along with the water. Examples are given in which (1) a trioxane/1,3- dioxolane/glycolic acid methyl ester copolymer is prepared in bulk, saponified with borax, dissolved in methylene chloride and dispersed in water; (2) a saponified trioxane/ethylene oxide/p glycidyl hydroxybenzoic acid methyl ester copolymer is dissolved in benzene and dispersed in water: (3) formaldehyde is polymerized using bis(glycolic acid methyl ester) formal as chain transfer agent, saponified with borax, dissolved in benzene and dispersed in water; (4) a trioxane/1,3 - dioxacycloheptane/# - propiolactone copolymer is saponified with KOH, dissolved in 1,1,2,2 -tetrachloroethane and dispersed in water; (5) a trioxane/1,3-dioxolane copolymer is grafted with methyl acrylate, saponified in NaOH/aqueous methanol and the methanol is distilled off to yield a polymer dispersion; and (6) a trioxane/1,3-dioxolane copolymer is grafted with isooctyl acrylate, saponified in 1,4- dioxane with sodium methylate, dissolved in benzene and dispersed in water.

Abstract: 1,259,658. Knitting. TEXPATENT G.m.b.H. 11 Nov., 1969 [26 Nov., 1968], No. 55180/69. Headings D1L and D1K. A knitted fabric produced on a circular knitting machine comprises loops which are transferred from their wales into an adjacent wale to prevent the formation of ladders, wherein the loops may be cast off from the needles or still on the needles immediately before transfer and wherein one leg of the loop crosses the other leg of the loop between the top and bottom of the loop due to twisting of the loop through 180 during transfer. As shown in Fig. 4 transfer bits 26 pick up loops Mv for transfer and move through the needles in the needle cylinder so that one leg of the loop is placed in the hook of the next needle. The transfer bit then rises so that the other leg of the loop is laid behind the needle hook. At this point two crossing points of the legs are produced, one inside the needle cylinder and one outside the needle cylinder. As the transfer bit is further raised to release the loop the crossing point outside the needle cylinder disappears but the crossing point K 1  inside the needle circle remains. The transfer bits are mounted in a rotating bed 66 eccentrically mounted with respect to the needle cylinder and this bed may be rotated with a peripheral speed less than or greater than that of the needle cylinder to transfer the loops either forwards or backwards.

Title: Device for lubricating wheel flanges of railway vehicles
IPC: B61K3/00
Filed: 1970-07-21
Abstract: 1311293 Movements of vehicles; utilizing P C LUTHAR 21 July 1970 35266/70 Heading B7J [Also in Division F2] The flanges of wheels of a railway vehicle are lubricated by pneumatically actuable oil sprayers which are actuated in response to the angular displacement between the bogie carrying the wheels and the vehicle frame so that only the flanges of the wheels on the outside of a curve are lubricated. Oil is sprayed on to the flange of a wheel 1 by a sprayer 4 secured to the bogie frame of the vehicle by brackets 3. Oil may pass from a reservoir 7 via a duct 28 to an inlet 6 of the sprayer. Air admitted by a valve 17, lifts a valve 11 whereby oil trapped in a chamber 9 is allowed to flow into a chamber 10 from which it is forced out by the compressed air to lubricate the wheel flange. When the air flow ceases, the valve 11 returns to its initial position admitting a further dose of lubricant into the chamber 9. Air is admitted to actuate the sprayer only when the vehicle enters a curve on the track. A plate 50 (Fig. 3) is secured to the bogie frame 29 and carries a pair of electrical contact rollers 32, 33. The underframe 30 of the vehicle carries three electrical contact plates 34, 36, 37, separated by insulating material 35. Roller 32 is always in contact with plate 34. When the vehicle enters a curve relative displacement between the vehicle and the bogie causes the roller 33 to be displaced from the insulating portion to contact either plate 36 or 37 depending on the direction of the curve, thereby completing an electrical circuit which operates an electropneumatic valve which admits air to the valve 17, causing the appropriate flange to be lubricated. In an alternative embodiment (Figs. 4 and 5, not shown) the supply of air admitted to actuate the sprayer is effected by a three way cock (20) operated by levers (45, 46) which move in response to displacement between the bogie and the frame.
